please show the solution
thank you

You can put this solution on YOUR website! I will show you 2 problems 1 and 4 and then you should get the pattern of how its done, remembering that consecutive intergers with a given variable a is a,a+1,a+2 etc., whereas consecutive odd or even intergers would be written as a,a+2,a+4 etc. with that background
1. lets callour consecutive integers a,a+1,a+2
:
a+(a+1)+(a+2)=18------>3a+3=18--->3a=15--->a=5 so integers are 5,6,7
4.lets call our 2 consecutive even integers a,a+2
:
a+(a+2)=38---->2a+2=38--->2a=36---->a=18...so integers are 18 and 20
have fun with the rest
